Abstract
Provided herein are methods and systems for controlling the number of ions in a batch of ions accumulated in an ion trap. The ion trap comprises one or more detection electrodes configured to detect image current signals from ions accumulated within the ion trap. An ion or group of ions passed to the ion trap is caused to impact upon one or more of the detection electrode(s) of the ion trap so as to provide a detected signal. An ion current or charge of the ion or group of ions is determined from the detected signal, and the determined ion current or charge of the ion or group of ions is used to control the number of ions in a batch of ions subsequently accumulated in the ion trap.
